Yun Liu
I am a professor at the College of Computer Science, Nankai University.
Previously, I served as a senior scientist at the Institute for Infocomm Research (I2R), A*STAR.
Prior to that, I was a postdoctoral researcher in the Computer Vision Lab at ETH Zurich,
working under the supervision of Prof. Luc Van Gool.
I obtained both my bachelor's and doctoral degrees from Nankai University in 2016 and 2020, respectively,
under the guidance of Prof. Ming-Ming Cheng.
My research interests focus on computer vision and deep learning.
